The third discussion draft of GPL version 3 is scheduled for release at 7 a.m. PDT on Wednesday, Brett Smith, a licensing compliance engineer for the Free Software Foundation said in a mailing list posting Monday. The current GPL 2 governs the rights and restrictions of many open-source and free-software projects, including high-profile ones such as the Linux kernel, Java and MySQL database. A 'last-call' draft is due 60 days after the third discussion draft, and the final GPL 3 will arrive 30 days after that, Smith said.
